Title: Structure of piston for internal combustion engine
Inventor: MATSUMOTO SATOSHI
IPC: C23C14/06
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To improve the abrasion resistance of a first ring groove part by forming the first ring part of a piston made of a cast iron of the heat and abrasion resistant alloy. SOLUTION: A first ring groove 2 is formed by welding the stellite powder as the heat resistant alloy to a groove 3 formed at the time of casting a crown part 1 while using plasma powder, and working the padding stellite 4. Since the first ring groove 2 is formed of the heat resistant powder alloy padded by the welding to the groove without generating the peeling of the heat resistant powder alloy, abrasion of the first ring groove 2 can be restricted. With this structure, first ring position can be heightened more, and a dead volume is reduced by the heightened quantity so as to improve the fuel consumption.

Title: Fuel injection control device for internal combustion engine
Inventor: MURAI ATSUSHI
IPC: F02D41/12
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent after burn by performing fuel cut for stopping fuel injection to an engine in a given deceleration operation condition, and on the contrary, by prohibiting the fuel cut for a given period during changeover from the actuation condition to the non-actuation condition of an auxiliary fuel injection valve. SOLUTION: A fuel cut means judges whether or not it is during fuel cut, and when it is not during fuel cut, the means judges whether or not a fuel cut condition, that is a given deceleration operation condition, is materialized or not. When it is materialized, a fuel cut prohibiting means reads value of a timer Ton for counting ON range residence time of an auxiliary fuel injection valve and value of a timer Toff for counting OFF range residence time, and judges whether Ton = 0 and Toff <= Tdelay (Tdelay is a given fuel cut prohibiting time). As a result, when Ton=0 and Toff <= Tdelay, that is, after changeover from the actuation condition to the non-actuation condition of the auxiliary fuel injection valve, the fuel cut is prohibited when within a given fuel cut prohibiting time Tdelay.

IPC: F17C13/00
Filed: 1982-09-17
Abstract: PURPOSE:To enable to extract parlite partially without modifying an above-ground cold tank having a double-shell structure and to facilitate repairing of the inner shell, by cutting the outer shell in the form of a round pipe, extracting perlite in the round pipe inserted into the perlite, repairing the inner shell, and then welding the hole into which the round pipe was inserted. CONSTITUTION:Reinforcing angles 4 are welded to the part of an outer shell 1 where freezing is caused and a round pipe 5 having an inner diameter enabling tank repairing operation is placed on the angles 4 in the manner that it is held in contact with the outer shell 1. Then, the outer shell 1 is cut along a circle having the same diameter as the round pipe 5 and a round plate 9 cut off from the outer shell 1 is dropped on the inside of the outer shell 1, whereafter the round pipe 5 is inserted into perlite 3 until it is held in contact with the outer surface of an inner shell 2. Then, perlite inside the round pipe 5 is taken out and the outer surface and other parts of the inner shell 2 located in the confine of the round pipe 5 is inspected and the round pipe 5 is removed after repairing. Thereafter, the tank repairing operation is completed by filling perlite in the hole made by the round pipe 5, lifting the round plate 9 by means of a wire 8, and welding the round plate 9 to the outer shell 1. Thus, it is enabled to repair cracks of the inner shell easily from the outside without extracting perlite wholly or extracting low-temperature liquid inside the inner shell 2.

Abstract: PURPOSE:To effect drying operation within a range in which misfiring is not caused in case the degree of abnormal combustion is small and stop the operation in case of abnormal combustion by a method wherein a burner internal pressure detecting means, detecting the fluctuation of internal pressure of the burner, which is changed in accordance with the fluctuation of the flow amount of fuel, is provided in the device. CONSTITUTION:When a detecting result given from the burner internal pressure detecting means 1 is permitted to regulate it within a given range from the reference value of the internal pressure of the burner in case of non-fluctuated flow amount of fuel, the operation of a ventilating device is controlled to regulate the ventilating amount of atmosphere supplied to the combustion system 3 of the burner. When the detecting result is not permitted to regulate it within a given range, the combustion in the burner 3 is stopped. According to this method, flicker of flame may be restricted and the drying operation of the lowest limit, in which the burner can be used without missing the fire, may be effected in case the pulsating combustion due to the pulsation of the flow amount of fuel is smaller than a predetermined value and there is few possibility of misfire or backfire. In case the pulsating combustion is larger than the predeterminded value, the operation of the drying machine may be stopped.
